NRF24l01 1.27mm Arduino Pro Mini Adapter board

    Not really a project, not my own design but I think this adapter board can be of use to many. The board was published by Kauz on www.thinkering.de.

    I breadboard a lot of pro-mini circuits to be MySensor'ized at a later stage and have been using the jModule frequently upto now, The jModule includes a 3.3V LDO and does the job well. However this adapter has the advantage that it breaks out all the pro-mini pin's in their original spot and keeps most of the form factor (you need to use a 3.3V pro-mini).

    A few pictures:

    The components

    Soldered with pin headers. The author soldered it "trough-hole" without headers.

    Comparison with jModule:

    Ready for 4 new MySensors projects 🙂

    Thanks for posting this! I am just getting past the breadboard/UNO stage and your timing is perfect. So far I have only used NRF24L01+PA+LNA and I want to build smaller units with NRF24L01+.

    Would it be possible for you to post your photo ("the components") with higher resolution? There are so many different NRF modules sold and I cannot see the details of the NRF module this adapter board will fit. Also can you share the source/model for the NRF module?

    Thanks again,

    Tim

    But those nrf24 modules are not the usual form factor, are they?

    @Grubstake Here you go. For the nRF24l01 modules search for "smd nRF24l01". I got them here. @gohan these small modules have given me less problems than the large one's.
    I marked the pad's where you connect Vcc (+) and Gnd(-) and on the small pads you can solder the capitor. It's where I used the tantalum one but you can probably fit a small electrolytics one (with wire) also.

  • Would it be possible to take 3.3 Volt from e.g. PIN 8 and GND from PIN 7?

    @flopp that is the intention you have the freedom to attach any pin, just be aware of the max sink sure current. I made a shortcut for ground on the other side of the board and the easiest route to the ftdi helder.
